I'm trying to use the following code to update a sql-table:

Sql sql(session);
		
sql * Update(SqlId(sqlTable))
(NAME, customer.name)
(NUMMER, customer.number)
(PRODUKT, customer.product)
(VERSION, customer.version)
(STANDORT, customer.location)
(ANBINDUNG, customer.connection)
(BEMERKUNG, customer.comment)
.Where(ID == customer.sqlID);

I get these error:

H:\Entwicklung\UPP\prohibisZA\prohibisZA.cpp(1274) : error C2660: 'Upp::Ctrl::Update' : function does not take 1 arguments
H:\Entwicklung\UPP\prohibisZA\prohibisZA.cpp(1282) : error C2228: left of '.Where' must have class/struct/union
prohibisZA: 1 file(s) built in (0:01.87), 1872 msecs / file, duration = 1919 msecs, parallelization 0%

There were errors. (0:02.48)

What went wrong?

Found out that this works:

Sql sql(session);
		
sql * SqlUpdate(SqlId(sqlTable))
(NAME, customer.name)
(NUMMER, customer.number)
(PRODUKT, customer.product)
(VERSION, customer.version)
(STANDORT, customer.location)
(ANBINDUNG, customer.connection)
(BEMERKUNG, customer.comment)
.Where(ID == customer.sqlID);

So is it ok to use SqlSelect, SqlInsert and SqlUpdate instead of Select, Insert and Update(which does not work)?

Well, there is unfotunate nameclash with Update that usually strikes when doing SQL in GUI - Ctrl has Update method, so that takes preference.

Update and SqlUpdate are equivalent.

But SqlSelect isn't equivalent to Select?

When i do this:

sql * Select(SqlId(sqlWhat)).From(SqlId(sqlTable)).Where(sqlWhere).OrderBy(sqlOrder);

Everthing is ok, but when i do this:

sql * SqlSelect(SqlId(sqlWhat)).From(SqlId(sqlTable)).Where(sqlWhere).OrderBy(sqlOrder)

I get the following error:

H:\Entwicklung\UPP\prohibisZA\prohibisZA.cpp(1069) : error C2440: '<function-style-cast>' : cannot convert from 'Upp::SqlId' to 'Upp::SqlS
	elect'
        No constructor could take the source type, or constructor overload resolution was ambiguous

prohibisZA: 1 file(s) built in (0:01.96), 1966 msecs / file, duration = 1997 msecs, parallelization 0%

There were errors. (0:02.63)

Yes, but it was not intentional, rather forgotten. Now fixed.
